Castr can run a pre-recorded video as a live stream, but its entry tier is built around a small amount of looping rather than a large library. As listed on Castr's site in September 2026, the entry plan allows one pre-recorded stream, 10 GB of storage, a 2 GB maximum file size and a four-hour maximum video duration.
That can be enough for a single devotional loop, study station or ambience channel if your master file fits. It becomes restrictive when you need several channels, a long source video, multiple backup files or a rotation that should continue while you edit the next version.
What Castr is very good at
Castr is useful when you need to send one live programme to several destinations or manage streaming as part of a wider broadcasting workflow. Its product is aimed at creators, organisations and broadcasters that may need more than a basic “play this file on YouTube” setup. The relevant distinction is that a service can be strong at live distribution while still having limits that matter for a single pre-recorded loop.
A 24/7 channel has a narrower requirement. You need a file to be accepted, stored, started as a broadcast, repeated or scheduled correctly, and kept running when your computer is shut down. You may not need a large collection of destinations or a full broadcast control room. The right question is therefore not whether Castr can stream video. It can. The question is whether the plan you are considering leaves enough room for the way you actually produce video.
For example, a small bhajan channel might have one four-hour programme containing devotional music, a static background and a short title card. That programme may fit the entry limits. A local news loop with separate morning, afternoon and evening files has a different shape. Even if each file is acceptable, one pre-recorded stream allowance does not automatically mean three independent 24/7 channels.
Castr can also make sense when you already have a live production workflow and want pre-recorded video to sit alongside it. The service's broader live-streaming features may be more relevant to you than the storage allowance. In that case, assess the plan as a broadcasting tool rather than assuming that its entry tier is a dedicated, unlimited video shelf.
Your content plan should come first. The 12 profitable 24/7 live stream ideas can help you decide whether one repeating programme is enough or whether your channel needs several distinct formats.
The entry-tier limits that affect a 24/7 loop
The four limits work together. Looking at only the file-size cap can give you a false sense that the plan will fit. A file might be under 2 GB but still be too long, or it might be short enough but leave too little storage for revisions and backups.
| Entry-tier item | Limit listed by Castr in September 2026 | What it means for a loop channel |
|---|---|---|
| Pre-recorded streams | 1 | One pre-recorded stream allocation, not an automatic allowance for several separate channels |
| Storage | 10 GB | Space for uploaded media within the plan; revisions and duplicate files use the same allowance |
| Maximum file size | 2 GB per file | A larger master must be compressed, divided or exported again before upload |
| Maximum duration | 4 hours per file | A five-hour or eight-hour source cannot be uploaded as one entry-tier pre-recorded file |
These figures are stated here as Castr's September 2026 listing for the entry plan. Plan pages can change, and the current Castr pricing page should be your final check before payment or production migration. Do not assume that a higher-looking storage number, a different stream type or a separate live-stream allowance changes the pre-recorded limits described above.
One stream is not the same as one file
A pre-recorded stream is the running broadcast allocation. The file is the media you upload into it. You might have several files in your storage area, but that does not mean you have permission to run several pre-recorded broadcasts at the same time. Conversely, one file can be used in one stream without solving the question of how the stream behaves when the file ends.
Ask Castr specifically whether the stream repeats the file continuously, whether it can use a playlist, and whether a replacement can be prepared without interrupting the active broadcast. These are operational details, not merely storage details. A plan that accepts your file may still require a different workflow from the one you imagined.
Ten gigabytes is working space, not just programme length
Storage is consumed by the files you upload, not by the words in your content plan. Suppose your main programme is 1.7 GB. You may still need a revised export, a clean backup, a version with a different intro and a short test file. Keeping all of them online can use the allowance quickly.
A practical rule is to keep one production master offline and upload only the file currently needed for the broadcast. Before uploading a replacement, remove old versions only after checking which file is active. Never delete a file simply because its name looks old. Confirm the active programme in the dashboard first, then make the change during a planned maintenance window.
The file-size limit depends on your export settings
A two-hour 1080p video with a high bitrate can be larger than a four-hour 720p programme. Resolution, frame rate, codec, audio settings and the amount of movement all affect the final file size. Duration alone is not a reliable way to predict whether a video will pass the upload limit.
For YouTube delivery, H.264 remains a practical compatibility choice in many workflows. The H.264 versus HEVC guide for 24/7 YouTube loops explains why a smaller file is not automatically the best file if your encoder, editing application or delivery service handles codecs differently.
Export a short sample before rendering the complete programme. Check its dimensions, frame rate, audio and resulting size. Then estimate the full export from the sample, leaving room below the hard cap rather than aiming to land exactly on it. A file that is technically under the limit can still be awkward to replace if a minor edit pushes it over.
The four-hour duration limit changes your programming
A four-hour cap is manageable for a single loop, but it affects how you design repetition. If your source programme is longer, divide it into sections only if the transitions still make sense and the service supports the required sequence. Splitting a calm rain programme may be harmless. Splitting a news bulletin in the middle of a report can make the channel feel broken when it repeats.
Shorter files also make repeated content more noticeable. A listener may hear the same opening chant, station ident or spoken greeting at predictable intervals. If you are building a devotional or lofi channel, plan the loop as a complete programme rather than treating a long upload as an afterthought.
How to test a loop before relying on it overnight
Do not judge the setup only by whether the upload completes. An overnight channel has several separate failure points: the file may not start, the broadcast may end at the wrong time, the video may not repeat, audio may fall silent, or the connection to YouTube may need to be restored.
Start with a copy of the exact file you intend to use. Confirm that the final duration is no more than four hours and the file is no more than 2 GB. Keep the original master on your computer or external drive, because an uploaded copy is not a substitute for an archive.
Next, connect the stream to the correct YouTube channel and check the privacy setting before going public. YouTube's official live-streaming help explains the platform-side workflow, including stream setup and broadcast controls. Use the official instructions for current account requirements rather than relying on an old screenshot or a forum comment.
Run a private or unlisted test long enough to observe the start, a normal playback section and the transition at the end. You want to know whether the file loops cleanly, stops, or creates a new broadcast. Watch from another device if possible. A creator who monitors only the dashboard may miss silent audio, a frozen image or a viewer-facing error.
Then test the practical replacement process. If the programme needs a corrected title card tomorrow, can you upload the new file without disturbing the current broadcast. If a file is removed to free storage, is the live stream still pointing to it. If the stream stops, what exact action restarts it. Write these steps down while the setup is fresh.
This is also where a local computer and a hosted workflow differ. A PC-based setup gives you direct control but depends on power, broadband, operating-system updates and the streaming application remaining healthy. The guide to 24/7 streaming without a PC covers those trade-offs in more detail. Whatever method you choose, a real test is more useful than a claim that a service is suitable for continuous streaming.
Reading a plan page for loop suitability in five minutes
You do not need to read every feature on a plan page to make an initial decision. Read it in this order.
1. Find the exact stream type
Look for “pre-recorded”, “recorded”, “on-demand” or similar wording. Do not count a general live stream as a pre-recorded stream unless the plan explicitly says that the feature applies. A plan can include several live destinations while allowing only one recorded programme.
2. Find the number of simultaneous streams
Check whether the number refers to destinations, channels, events or pre-recorded streams. These are not interchangeable. If you operate one YouTube channel, one stream may be enough. If you operate a devotional channel and a separate ambience channel, you need the plan to address two concurrent broadcasts rather than merely two uploads.
3. Find storage and file limits separately
Storage answers how much media can remain in the account. File size answers how large one upload can be. Duration answers how long one video may run. Treat all three as separate tests. Passing one does not imply passing the others.
4. Look for the behaviour at the end of the file
A 24/7 requirement depends on what happens when the source reaches its final frame. Does it loop, stop, return to a playlist, or require another event. If the plan page is unclear, look at the vendor's documentation or ask support a direct question with the file duration and intended YouTube workflow.
5. Check renewal and upgrade consequences
If the entry plan fails only because of storage, an upgrade may solve the immediate problem. If it fails because you need multiple simultaneous pre-recorded channels, you may need a different plan or a different workflow entirely. Do not upgrade based on a larger storage figure without confirming that the stream-count, file-size and duration limits also change.
Save a copy of the relevant plan details with the date you checked them. This is useful when a project is handed to another person and when a limit changes later. Castr's support documentation is the appropriate place to check current feature behaviour, while the pricing page is the place to check the current plan presentation.
Enterprise reputation and what it costs
Castr has a reputation for serving more demanding broadcast workflows than a simple personal live-stream tool. That can matter if you need several destinations, operational controls, team involvement or a workflow that has to fit an organisation's existing broadcast process. It does not remove the need to check the exact pre-recorded limits for the plan you will actually use.
For enterprise customers, the important question is not whether a sales page sounds broad. Ask for the limits in writing. Request the number of concurrent pre-recorded streams, included storage, maximum file size, maximum duration, retention rules and what happens if a stream disconnects. Also ask which features are included in the quoted arrangement rather than assuming that an enterprise label includes every capability.
As listed on Castr's site in September 2026, enterprise pricing is not presented as one universal public amount; it is handled through a custom quotation. That means you should not use a guessed monthly figure in your channel budget. Ask for the full recurring cost, any setup or onboarding charge, the billing period and the consequences of exceeding included usage.
Enterprise may be the right direction for a broadcaster with several channels and a defined support process. It may be unnecessary for one small YouTube loop. A local business running a single information channel should first describe its actual operational need: one file, one stream, one YouTube destination, and a clear recovery plan. A larger plan is not automatically better if the extra features do not solve the problem you have.
Decision table for a 24/7 YouTube loop
| Your situation | What the Castr entry limits suggest | Sensible next step |
|---|---|---|
| One programme under four hours and under 2 GB | The basic media limits fit on paper | Test the complete broadcast, including the end-of-file behaviour |
| One programme over four hours | The file cannot be uploaded as one entry-tier item | Shorten it, divide it carefully, or ask Castr about a plan with a higher duration limit |
| One programme over 2 GB | The upload exceeds the listed per-file cap | Re-export with suitable settings and test quality, or check another plan |
| Several programme versions and backups | The 10 GB allowance may become working-space pressure | Keep masters offline and upload only active media, or confirm expanded storage |
| Two or more simultaneous YouTube loops | One pre-recorded stream is not enough for the stated use | Ask for the exact concurrent-stream allowance before choosing a plan |
| A news or business channel needing frequent edits | A small file cap can make each replacement part of the workflow | Use a repeatable export process and test replacement without ending the live broadcast |
| A channel that must run with your computer off | A hosted workflow may remove local-device maintenance, but the plan still needs testing | Verify restart, alerting and replacement behaviour rather than assuming continuity |
The table is a screening tool, not a promise that a particular arrangement will work. YouTube can impose its own account, content and live-stream requirements. Review the current YouTube live-streaming policies before making the channel public, and keep rights documentation for music, footage and images used in the programme.
For creators who want the computer switched off and do not want to maintain a local encoder overnight, StreamNeo removes the specific burden of uploading a file once, connecting the YouTube stream and leaving the broadcast to run with automatic monitoring and restart. It is YouTube-only, so it is relevant when that is your destination, not when you need a broadcast operation.
A practical choice for your channel
Choose the Castr entry tier when one pre-recorded stream is genuinely enough, your programme is no more than four hours, your file remains below 2 GB, and 10 GB gives you comfortable working space. “Comfortable” matters. If every edit requires deleting the previous upload and you have no room for a test copy, the plan may technically fit while remaining unpleasant to operate.
Ask for clarification before committing when the plan page does not explain looping, playlists, replacement, stream recovery or the difference between a live stream and a pre-recorded stream. Put the questions in writing. A clear answer about your exact channel and file is more useful than a general statement that the service supports 24/7 streaming.
If the entry tier does not fit, compare the cost of changing your files with the cost of changing the service. Re-exporting a video may be simple for a static ambience station and disruptive for a news loop. Moving to a higher tier may solve storage but not multiple-channel needs. A different workflow may be more suitable when you need several independently managed programmes.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Can I run a four-hour file continuously on Castr?
The entry plan listed by Castr in September 2026 allows one pre-recorded stream and a maximum file duration of four hours. Confirm how the file behaves when it reaches the end, then test the complete loop privately or unlisted before relying on it overnight.
Does 10 GB of storage mean I can run several pre-recorded channels?
No. Storage is space for uploaded media, while the plan's pre-recorded stream allowance concerns the broadcast itself. Castr lists one pre-recorded stream on the entry plan, so ask about concurrent streams if you need separate channels.
What if my video is under four hours but larger than 2 GB?
It will still exceed the listed per-file limit. Re-export it with settings that reduce the size while retaining acceptable picture and audio quality, or confirm whether another Castr plan supports a larger file before rebuilding your workflow.
Is Castr suitable for a small YouTube devotional or ambience channel?
It can be suitable when one programme fits the four-hour and 2 GB caps and you can work within the 10 GB storage allowance. Run a real test of playback, looping, audio and recovery first, and check Castr's current plan details because limits can change.
